我正在使用一个利用Picasso下载图像的库(SliderLayout),但我不确定如何从下载的图像中提取宽度和高度。有什么想法吗?
imageURLs = getActivity().getResources().getStringArray(R.array.image_urls);
imageSlide = (SliderLayout) view.findViewById(R.id.gallery_slider);
ArrayList<DefaultSliderView> slides = new ArrayList<DefaultSliderView>();
for(int i = 0; i < imageURLs.length; i++){
currentSlidePosition = i;
DefaultSliderView slide = new DefaultSliderView(getActivity());
slide.image(imageURLs[i]);
//need width and height of image downloaded here
slides.add(slide);
imageSlide.addSlider(slide);

一种常见的方法是使用Picasso加载:
Picasso.with(this).load("http://").into(new Target() {
@Override
public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
int width = bitmap.getWidth();
int height = bitmap.getHeight();
imgView.setImageBitmap(bitmap);
}
@Override
public void onBitmapFailed(Drawable errorDrawable) {
}
@Override
public void onPrepareLoad(Drawable placeHolderDrawable) {
}
});
